International Rectifier was an American power management technology company manufacturing analog and mixed-signal ICs, advanced circuit devices, integrated power systems, and high-performance integrated components for computing. On 13 January 2015, the company became a part of Infineon Technologies.[1]

IR's products, as a part of Infineon Technologies' overall semiconductor portfolio, continue to be used in many applications including lighting, automobile, satellite, aircraft, and defense systems; as well as key components in power supply systems in electronics-based products that include especially microcomputers, servers, networking and telecommunications equipment.

History

In the 1950s the company commercialized germanium rectifiers (1954) and created the first silicon-based rectifier (1959). In 1974 it developed the first power and Darlington transistors which used glass passivation. In 1979 it developed first hexagonal power MOSFET Then in 1983, it developed the first intelligent power ICs.[citation needed] In 1983 it lost a patent infringement lawsuit over the rights to doxycycline to Pfizer, Inc., resulting in a judgment of $55 million to Pfizer. To avoid bankruptcy, International Rectifier gave Pfizer its animal health and feed additive businesses.[2][3] In 2000, it developed FlipFET wafer packaging. Two years later, it developed DirectFET, a MOSFET packaging technology developed to address thermal limitations found in advanced computing, consumer, and communications applications.[citation needed]

In 2003, it developed iMOTION Integrated Design Platform for motor control applications. In 2006, SmartRectifier IC was introduced for AC/DC applications. In 2007 the company launched SupIRBuck integrated voltage regulators. In 2008 a GaN-based power device platform was introduced. In 2011, it introduced PowIRstage devices and CHiL digital controllers. In 2012, it followed by launching micro-integrated power modules for motor control applications and COOLiRIGBTs for automotive.

In 2014, the company was bought by Infineon Technologies for $3 billion.[4] By 2015, International Rectifier had officially become a part of Infineon Technologies [5]

Manufacturing

International Rectifier also had wafer fabrication and assembly facilities around the world. The locations include:
